So question.

Since I had all 3 I figured Id try and install 4. And I did, and the funny thing is (besides when Im in port with alot of trees around and such) the game actually works BETTER than III, I mean I did a mission quickly and where as 3 had problems (small framerate drops) when I moved in free cam around a huge fleet, 4 didnt have that problem, AND the water reflected how it was supposed too AND the graphics are a bit higher, hmmm
